Amazon Redshiftを使用するプロジェクトにQueryDSLを追加しようとしています。私はQueryDSLがRedshiftをサポートしているのかどうか分かりません。おそらくここでは間違っています。私は、関連する抜粋下記参照、Qクラスにコンパイルエラーを取得しています：RedDSP設定のQueryDSL
TABLE DDL（赤方偏移）
CREATE TABLE users_follow (

QueryDSL 4.1.0とのPostgresを使用して私のために正常に動作する - それはあなたの問題の根本的な原因である「逆」の外部キーを生成しません。しかし、私はそれを可能にするオプションを見つけることができませんでした。あなたは現在のバージョンを試しましたか？または少なくとも4.0.8？ –
@a_horse_with_no_name 4.1.0と試してみると、問題は残ります。 – fred
